一、前言多金属鑛床,即一般所指铅锌鑛床,其中含有Pb,Zn,Cu,Ag等元素以及其他有用伴生组份,因其组份较多故称为多金属鑛床。其中所含的主要有用伴生组份是:Cd,Bi,Sb,In,Ge,Co,Mo,(?),S,CaF_2等等;虽然它们含量不高,但由于种类很多,且工业价值大,并与主要组份(Pb、Zn)伴生在一起,故引起鑛床评价时的注意。二、有益伴生组份的产状 I. INTRODUCTION Polymetallic deposits, commonly referred to as lead-zinc deposits, contain elements such as Pb, Zn, Cu, Ag and other useful associated components and are called polymetallic deposits because of their large composition. The main useful companion components contained in it are: Cd, Bi, Sb, In, Ge, Co, Mo, (?), S, CaF 2 and so on; although their content is not high, , And associated with the main components (Pb, Zn) together, it caused the attention of the deposit evaluation. Second, the occurrence of beneficial associated components
